revese osmosis setup

I am looking into installing a reverse osmosis system under my kitchen sink then running a line into my grow room in the basement. What type of line would I have to feed into the room? I haven't purchased a ro system yet ... any suggestions? As far as my hydro setup I am leaning towards the ebb and gro system, which would require me to fill up the 50 gallon reservoir when changing nutrients.

We have a three stage system in the laundry room and it takes about 8 hours to fill a 32 gallon reservoir. The time is long but it removes everything from the water. Literally 0 PPM. They come with a standard 1/4" tubing that's about 3' long. You can buy rolls of 1/4" tubing from Lowes or Home Depot in the plumbing/sprinkler sections.

my 0 ppm system takes even longer than that, depending on your houses water pressure it might be worth it to buy an extra reservoir. you can rig up a float system to aviod any overflow.

Yah we have it hooked up to a Y adapter with the washing machine. Has a little bit more pressure than the rest of the house.
